Özet:
Creep criteria for designing with geosynthetics as earth reinforcement were developed from in-air testing. It has been observed many times that geosynthetically reinforced soils (GRS) do not exhibit creep behavior predicted by the in-air tests. In fact, significant long-term geosynthetic creep in GRS features built with granular soils is unreported. This paper describes development of a testing device and testing protocol to measure performance of GRS composite behavior. Testing included geosynthetically-reinforced granular and cohesive soils as well as unreinforced soils. Loads and reinforcements were varied.
